Pixar co-founder Alvy Ray Smith in Wired:
We know what Moore’s Law is and how it works, but not many people reflect on why it exists. Yes, there are often physical barriers to innovation. But there’s no imminent physical barrier to the realization of a bit: A bit is merely presence or absence of something, say a voltage, which means it can get exponentially smaller. So with no physical limitation, Moore’s Law reflects the top rate at which humans can innovate. If we could proceed faster, we would.
There are no shortcuts at the edge of discovery and invention.
